Huh.
I have the disc version of nfsu 1, nfsu2 and nfs most wanted. Nfsu2 runs smoothly, had to have it in windowed mode to show that I use Win10.
And I have not ran into any trouble when installing the game, no compatibility errors or anything :S
No error when running the game either. And my version is retail as you can see by the pictures.
And I do not have any no-cd patches running either. Though I'm not OP, but how could I get the game running without any hacks?
